Description: A buffer overflow vulnerability was reported in the RealOne Player and RealPlayer 8 in a data compression library used to process PNG images. A remote user can cause arbitrary code to be executed.
RealNetworks reported a heap corruption vulnerability on the RealOne Player and RealPlayer 8. A remote user could create a specially
crafted Portable Network Graphics (PNG) file that, when loaded by the target user, would cause arbitrary code to be executed on
the target user's computer.
According to the report, the flaw resides in the RealPix component of the Player in an out-of-date
data compression library.
RealNetworks also announced that some other unspecified vulnerabilities were discovered during an internal
review of the RealOne Player source code.
The following player software is affected:
RealOne Player and RealOne Player v2
for Windows (all language versions), RealPlayer 8 for Windows (all language versions), RealPlayer 8 for Mac OS 9, RealOne Player
for Mac OS X, RealOne Enterprise Desktop Manager and RealOne Enterprise Desktop (all versions).
RealNetworks indicates that the
Helix DNA Client is not affected.
RealNetworks credits Carlos Sarraute and Juliano Rizzo of Core Security Technologies with discovering
these flaws.
|
Impact: A remote user can supply an image file that, when loaded or viewed by the target user's Player, will cause arbitrary code to be executed on the target user's system. The code will execute with the privileges of the target user.
|
Solution: Updates are available for Windows RealOne Player (6.0.10.505), RealOne Player version 2 (6.0.11.853), and RealPlayer 8 (version 6.0.9.584);
